Mounting structure of planet roller and lifting appliance

Abstract

The invention discloses a mounting structure of a planet roller and a lifting appliance. The lifting appliance comprises a roller connecting part, a lifting ring connecting part and a connecting transition part, the roller connecting part is provided with a first mounting part, the planet roller is provided with a connecting area, the first mounting part and the connecting area are correspondinglyarranged, and the first mounting part is connected with the connecting area through a connecting piece to realize mounting of the roller connecting part and the planet roller. The lifting ring connecting part is located above the roller connecting part, a second mounting part is arranged on the lifting ring connecting part, and the second mounting part is used for mounting a lifting ring. The roller connecting part is connected with the lifting ring connecting part through the connecting transition part. The central axis of the first mounting part is perpendicular to the central axis of the second mounting part. By means of the scheme, when the planet roller is lifted, the central axis of the planet roller is perpendicular to the central axis of the lifting ring, it is guaranteed that when the novel planet roller is lifted, the direction cannot be changed, and mounting of the novel planet roller becomes simple and convenient.

Description

technical field [0001] The invention relates to the field of rolling mills, in particular to a mounting structure for a planetary roll and a hanger. Background technique [0002] The three-roll planetary rolling technology in the production of copper pipes for air-conditioning and refrigeration in my country is basically a mature technology commonly used in the industry. Most of the 90-type three-roll planetary rolling mills equipped are used for rolling 90mm series ingots , The three-roll planetary rolling mill has been applied to rolling various pipe fittings. For example, high phosphorus copper tube, oxygen-free copper tube, etc. In the prior art, a three-roll planetary rolling mill generally consists of a fixed frame, a sun gear, a moving rotary pan, three rolls distributed at 120° and loaded into the pan, a gear transmission mechanism, and a central lubrication system. Among them, the roll is generally in the shape of a cone, including a cylindrical area, a bite reduci...

AI Technical Summary

Problems solved by technology

This will cause the value of the roll to be underutilized and increase the production cost of the copper pipe

[0004] In order to solve the above problems, the applicant has improved the structure of the planetary roller. For details, please refer to the application number: 2020224491082, the application name: a utility model patent application for an end-face toothed disc type planetary roller, and the application number: 2020224491330 , the name of the application is: a utility model patent application for a convex ring block type planetary roll on the end face. When the roll is lifted, the central axis of the planetary roll will coincide with the central axis of the lifting ring, which changes the installation direction of the planetary roll. Since the assembly position used to realize the installation of the roll shaft and the planetary roll is fixed, if the position of the planetary roll is changed The installation direction will make the installation of the roll shaft and the planetary roll complicated and difficult. Therefore, it is necessary to invent a new type of special hoist for the planetary roll to ensure that when the planetary roll is hoisted, the center axis of the planetary roll and the center of the lifting ring It is necessary to set the axis vertically
